Early Actions of Gibberellic Acid on the Embryo and on the Endosperm of Avena fatua Seeds.
Gibberellic acid at 0.1 mum stimulates amylase synthesis in dormant Avena fatua seeds without inducing germination; at 0.5 mm it enhances biosynthesis of proteins and RNA in both the embryo and the endosperm and utilization of the endosperm sugars by the embryo. These events occur in early hours (0-14th hour) and prior to germination, which begins 24 hours after gibberellic acid application. Th...
متن کاملCorrelation between the Lipid Composition and the Responsiveness of Avena sativa Stem Segments to Gibberellic Acid.
The lipid composition of Avena sativa stem segments was manipulated using BASF 13-338 (formerly Sandoz 9785) and growth temperature, in order to establish whether there were correlations between responsiveness of the tissue to gibberellic acid (GA(3)) and the presence, before hormone treatment, of specific lipid components. High correlations were obtained between GA(3)-induced growth and total ...
متن کاملReference gene selection for molecular studies of dormancy in wild oat (Avena fatua L.) caryopses by RT-qPCR method
Molecular studies of primary and secondary dormancy in Avena fatua L., a serious weed of cereal and other crops, are intended to reveal the species-specific details of underlying molecular mechanisms which in turn may be useable in weed management. Among others, quantitative real-time PCR (RT-qPCR) data of comparative gene expression analysis may give some insight into the involvement of partic...
متن کاملCharacterisation of Avena fatua populations with resistance to multiple herbicides
Avena fatua (wild oat) populations with resistance (R) to one or more herbicides have been described in numerous cropping systems worldwide. We previously reported that the R3 and R4 wild oat populations from Montana, USA, were resistant to four herbicides representing three different modes of action: tralkoxydim [acetyl-CoA carboxylase (ACCase] inhibitor), imazamethabenz and flucarbazone [acet...
متن کاملPlant growth and phenolic compounds in the rhizosphere soil of wild oat (Avena fatua L.)
The objectives of this study were to determine the pattern of dry matter (DM) accumulation and the evolution of phenolic compounds in the rhizosphere soil from tillering to the ripe seed stages of wild oat (Avena fatua L.), a widespread annual grassy weed. Plants were grown under controlled conditions and harvested 13 times during the growing season. At each harvest, shoot and root DM and pheno...
